Yeah, when it comes to thrash riffs, I think that Skeletonwitch is outclassed by a few other bands, most notably Vektor. But still, there are some Skeletonwitch songs that really get me banging my head.

Black metal is an awesome genre but it can be very hard to get in to. It took me years to learn how to appreciate it. There are a ton of great bands out there. I would suggest the following bands that have songs with great melodies:

There are of course a ton more out there, but no need to overwhelm you. I am sure our fellow shreddit denizens have their own suggestions. Good luck getting into black metal, it is a genre full of atmospheres, texture, and emotion, but also often can be just as demonstrative of the technical skill that you see in other genres.

Metalcore is better suited for /r/metalcore. Thank you for your cooperation.

Oh, is it deathcore? I don't care, don't post it here. Save it for /r/deathcore.

As for the song itself, I don't like the tone of the guitars. The drums are atrocious. Did you throw in the "melodic" singing bits just to get the girls? Don't answer that. This song is repetitive and predictable. This is derivative and is certainly stretching the definition of metal.
